Which outcome occurs when UV radiation excites electrons to antibonding molecular orbitals in a polymer material?

💡 Explanation

When UV radiation excites electrons to antibonding orbitals, bond weakening occurs in the polymer chains because antibonding orbitals counteract the stabilizing effect of bonding orbitals, leading to bond breakage. Therefore chain scission results, rather than strengthening, stabilization, or conductivity which require different electronic effects.
